why choose dram?

The Kove® engineering team regularly evaluates current and emerging solid state media, such as Flash, Phase Change Memory, and Memristors, among many others.

DRAM is the Highest Performance Media

No one debates that DRAM provides the lowest latency, highest performance media. RAID controllers, Ethernet NICs, spinning disk and Flash devices, all use DRAM buffers. Server main memory uses DRAM because it can satisfy the demanding requirements of the CPUs.

Alternative Media

Other technologies optimize for capacity, with resulting performance tradeoffs that make them inapplicable for use as actual computer memory. Consider:

Spinning Disk. Achieving the best performance on spinning disk requires “short stroking.” In short stroking, only the outer rim of the platter stores data, in order to ensure the best possible sequential performance. What is lost in capacity is gained in performance. Gaining performance reduces capacity, and gaining capacity reduces performance.

Kove® Memory Mesh Advantages

Kove® memory meshes use DRAM.

Unlike spinning disk and Flash, the Kove® XPD® family will not meaningfully degrade performance, whether at 10% occupancy or at 95% occupancy. Short stroking is not necessary. Unlike local memory, Kove® memory meshes scale to the full 64 bit address space, scaling right across box boundaries whenever necessary, linearly scaling performance and capacity.

Specifically, the Kove® XPD® product line provides consistent IOPS for variable I/O patterns, world record-setting bandwidth, and the lowest available real world latency performance.

The Kove® XPD® technology just works, and when performance matters it just works better.
